Brain imaging differences in infants at genetic risk for Alzheimer'sResearchers from Brown University and Banner Alzheimer's Institute have found that infants who carry a gene associated with increased risk for Alzheimer's disease tend to have differences in brain development compared to children without the gene. The study, published in JAMA Neurology, demonstrates some of the earliest developmental differences associated with a gene variant called APOE-E4, a common genotype and a known risk factor for late-onset Alzheimer's.http://medicalxpress.com/news/2013-11-brain-imaging-differences-infants-genetic.html

Alzheimer's disease & dementiaTue, 24 Sep 2013 11:49:36 EDTnews299242167Memory-related brain network shrinks with agingBrain regions associated with memory shrink as adults age, and this size decrease is more pronounced in those who go on to develop neurodegenerative disease, reports a new study published Sept. 18 in the Journal of Neuroscience (Vol. 33:38). The volume reduction is linked with an overall decline in cognitive ability and with increased genetic risk for Alzheimer's disease, the authors say.http://medicalxpress.com/news/2013-09-memory-related-brain-network-aging.html

Psychology & PsychiatryThu, 05 Sep 2013 06:45:57 EDTnews297582333Could a treatment for Parkinson's disease help the social impairment of diseases like autism?A stressful pregnancy might be the last thing a future mother needs, but it is to her unborn baby that this stress spells real trouble. All because stress hormones (called glucocorticoids or GCs) can change foetal brain development, causing the new individuals to develop serious behavioural and/or emotional problems. Despite this danger we remain far from understanding how GCs work. But now a study in rats by a Portuguese team has discovered that the prenatal (before birth) effect of GCs on behaviour is linked to problems in dopamine (a brain messenger). Surprisingly, they also found that it is possible (and easy) to reverse the abnormal behaviours seen in these individuals, a discovery with possible implications for neurological diseases like autism and attention-deficit hyperactivity disorder (ADHD).http://medicalxpress.com/news/2013-09-treatment-parkinson-disease-social-impairment.html
